What is interesting is that _default_ Debian linux kernels have fbcon
enabled as a module and they work.
IIRC, fbcon and vesafb are included into initrd. But there's some some
configuration required. If you look into the default
kernel's /lib/modules/`uname -r` directory, you'll find that there's a
folder named initrd/ which contains the vesafb.ko module.
Can someone explain how that works and how to get that functionality when
rolling out our own custom kernels.
(I roll out a custom kernel to select Pentium M as the Processor)
